feature -- Enumeration

	Replace: INTEGER = 0
			-- One clipping region is replaced by another.

	Intersect: INTEGER = 1
			-- Two clipping regions are combined by taking their intersection.

	Union: INTEGER = 2
			-- Two clipping regions are combined by taking the union of both.

	Xor_mode: INTEGER = 3
			-- Two clipping regions are combined by taking only the areas enclosed by one or the other region, but not both.

			-- Specifies that the existing region is replaced by the result of the new region being removed
			-- from the existing region. Said differently, the new region is excluded from the existing region.

	Complement: INTEGER = 5
			-- Specifies that the existing region is replaced by the result of the existing region being
			-- removed from the new region. Said differently, the existing region is excluded from the new region.
